series of cylinders by having the current therefrom electro-magncticallydistributed to said cylinders.

This invention consi in a source of high tension current, preferably aninduction coil, the prin'iary winding of which may be connected to aplurality of sources of low tension current, of a series of spark-plugs,a separate circuit between each spark-plug and the secondary winding ofthe induction coil, an electro-n'iagnetic switch in each said circuit, acurrent distributer operated by an engine, a circuit connecting thewinding of each electroinagne-tic switch to the primary winding of saidinduction coil and to said distributer, which circuits are closed in sc'quence by said distributor as a current is desired at the spark-plugs toexplode the 'by the arm 3 secured to the shaft 4 which is driven by theengine. The arm 3 and shaft 4 may be grounded by the wire 5. Wires 6, 7,8 and 9 connect to the various contacts 2 and to the windings of the magnets 16, 17, 18 and 19, respectively. -The opposite ends of the windingsof these magnets connect to the bus-bar 15 by wires 14.

a. current passes to its winding, draws up an armature 26, 27, 28 or:29, which is connected. to the bus-bar 21 by means of a wire 36, 37, 38or 39, and when the armature is drawn up against the core, a hightension current will pass from the bus-bar 21 to one of the spark plugs46, -17, 48 01' d9 (of which there is one for each cylinder of theengine), over the wire 56, 57, 58 or 59, ac-

cording as the arm 3 engages with the contact 2 at the end of the wire6, 7, 8 or 9. The spark-plugs may all be of any well known constructionand their cylinders are grounded, this fact being indicated by the wires2 although the engine itself constitutes the ground The primary winding30 of the induction coil connects to the vibrator 31 and to the switcharm 32. A storage battery 33 connects to the contact 34 and is groundedby the wire 35. A magneto 10 connects to the contact ll of this switchand is grounded by the wire 12. The

magneto will preferably be driven by the engine and produce analternating current. The contact point 43 of the vibrator connects tothe bus-bar 15 by means of the wire 44. I

The secondary winding 50 of the induction coil connects to the bus-bar21 by means of a wire 51 and to the wire 44 by means of a. wire Whilefour spark-plugs are shown, it will be understood that this number maybe varied as desired.

As the arm 3 engages the contact 2, at the end of the wire 6, a currentwill flow from the magneto 4:0 over the primary winding of the inductioncoil to the bus-bar 15, over the Wire 14, the winding of the magnetil6,causing its core to draw up the armature 26, then over the wire 6, thearm 3 and wire 5 to ground. The secondary current will be from the wire44, over Wire, 52, the secondary winding 50 and Wire 51 to the bus-bar21, thence over the wire 36, switch 26 and wire 56 to the spark-plug4L6.

Each spark-plug thus receives a current during such time as the arm 3engages the contact 2 at the end of the main Wire of the primary lead 6,7, 8 or 9 of that particular spark-plug, and this current stops as soonas this engagement is broken, even if the magnet should be slow inreleasing its armature, which slowness may be desirable on account ofthe interruption in the primary circuit by the action of the vibrator31. As only one induction coil is employed,

absolute synchronism is assured, which is impossible where aseparateinduction cell is used for each spark-plu By mounting the pivot (3() ofthe armature 65 on a metal frame 61 quite ,near the core rotatable toadvance or retard the ignition sparks in the usual manner, this beingindicated by the arm 66 and the arrows leading therefrom. Details ofconstruction are omitted for the reason that'all the elements employedare wellknown, the novelty residing entirely in the combination orassembling of these elements.
